... these theoretical results, backflow vortex cavitation, which occurs around the center of the backflow vortices on a rotating inducer as a representative of axial pumps or compressors, was observed. The backflow vortex cavitation is visible; therefore, d, , and N become quantitatively measurable. The test inducer...
